Hello Dear Friends :-)
 i have a problem with ACER Aspire 7110
i need to Re-install the windows , laptop restarts on windows loading
Boot Device set to HDD
i can't Enter the BIOS because it have Password
on BIOS page i can see "Phoenix trustedCore(tm) Setup Utility"

1-Removing the BIOS Battery didn't help , i removed it for more than 1 Day
2- can't use USB/CD/DVD because First Boot is the HDD
3-can't use the BIOS Password Cracker /Hacker /Remover /Finder tools because system restarts middle of Loading
4-Global Phoenix Passwords didn't worked ( PHOENIX-phoenix-CMOS-cmos-BIOS-bios)



so how i can bypass the BIOS PW to change the Boot priority ?!
Thanks

If you own/have permission to remove the password there is one utility if you can get into windows that will remove the password.

command string:
ioperm.exe -i and then Cmospwd_win.exe /k

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

On systems that use a security chip there is virtually no way to reset a forgotten password ==> the security chip makes these VERY secure systems;  but you do NOT want to forget your password.    The solution is a replacement of the motherboard -- a several hundred dollar "repair".

HOWEVER, since you don't actually need to get to the BIOS -- you just need to install Windows -- you can bypass the issue.    Remove your hard drive;  attach it to another system [using a USB bridge device like this:  http://www.newegg.com/Product/Product.aspx?Item=N82E16812232002&cm_re=vantec_usb_ide-_-12-232-002-_-Product ];  and reformat the hard drive.     Now replace it in the Acer ... and when it tries to boot and doesn't find a bootable partition it will go to the next device in the boot order -- which should be your Windows CD.
